To modify the LAN group you just have to click on the name. You can insert a new origin group clicking on Insert link.
Settings:
Machine groups
: You can associate to this group an existing machine group;
Machines
: Lists the machines that are registered in IPBrick and provides direct association to the origin group;
IP subnets
: Provides subnets association, defining the network IP and its mask;
IP machines
: Provides machine association to the group by IP;
IP ranges
: You can set IP ranges with proxy access.
By default the proxy has a source group called LAN where only the IP Subnet is used (Figure 4.7).
If you choose the proxy with authentication mode, it's possible to filter the web access's not only by the machines IP but also using LDAP. In Figure 4.8 we can see an example of a source group represented only by a LDAP group.
